Presentation
Performed routine consultation with some nodules distributed in the body, the largest ones on the lower limbs. Asked MRI for diagnosis.
Patient Data
Lesions with expansive characteristics on the left popliteal fossa, with lobed appearance and relatively preserved contours, measuring 8 cm in larger diameter and several other smaller lesions with an average size of 3 cm. Most lesions are observed along the paths of the tibial-fibular nerve bundles. Oedema at connective tissue and adjacent muscles, greatly in the lateral gastrocnemius.
Case Discussion
Biopsy of the largest lesion demonstrated neurofibroma. No surgery was performed. The patient kept following her underlying pathology (NF1).
Neurofibromas are benign nerve sheath tumours of the peripheral nervous system. They affect a single peripheral nerve or multiple nerve bundles (plexiform neurofibromas). These tumours remain benign throughout life and do not become malignant cancers.
